  I was writing the expression for varying gravity vector along the radius. While I was specifying the units as of gravitational acceleration (m/s^2), it was showing error that m is not defined. I am attaching the screenshot of the same.

  Try writing it like this:
  (3.98[m^2/s^3]*10^14)/(radius[m]^2)
  If the quantity radius already has units, no need to specify [m] after it. Also, no need to specify the units for gravity. Click on refresh and confirm that you have the right units.
